Accéléromètres

Les accéléromètres utilisent un système ressort-masse pour générer une force proportionnelle à la vibration. Brüel & Kjær propose une large gamme de solutions d'accéléromètres qui répondent à des besoins et applications variés. Cette adaptabilité est évidente dans la gamme de transducteurs conçus pour des environnements, des industries, des tâches et des conditions spécifiques, ainsi que des instruments à usage général qui offrent une large plage de fonctionnement.

OVER 70 YEARS OF INNOVATION

In 1943, Per V. Brüel, developed the world's first commercial piezoelectric accelerometer from Rochelle salt crystals.

In fact, many of the accelerometers on todays market are based on technology invented by Brüel & Kjær.

HISTORY OF THE ACCELEROMETER 

Accelerometer Types

Brüel & Kjær Accelerometer Types

Brüel & Kjær offers a broad spectrum of vibration measurement solutions that respond to varying needs and applications. In measuring acceleration, displacement and velocity, we provide a range of high-quality accelerometers, designed for specific environments, tasks and operating conditions.

 

Charge accelerometer

Charge Accelerometers

A charge‐type piezoelectric accelerometer is robust and designed specifically for high‐temperature vibration measurement. The unique design of our charge sensors provide a high dynamic range, long‐term stability and ruggedness.

Available in single axial and triaxial configurations.

CCLD Accelerometer

CCLD Accelerometers

A CCLD accelerometer is designed specifically to make vibration measurement easy because the needed preamplifier is built into the accelerometer unit. It features low impedance output enabling the use of inexpensive cable and can drive long cables.

Available in single axial and triaxial configurations.

Industrial Accelerometer

Industrial Accelerometers

An industrial accelerometer - with its rugged design - is both robust and reliable and covers a wide range of permanent vibration monitoring applications including operations in wet, dusty and potentially explosive areas.

Charge and CCLD types are both available. Charge types are especially excellent for high‐temperature measurements.

Important Accelerometer Specifications 

When selecting your accelerometer, please consider the following specifications according to your test application and environment.

Highlighted specifications to consider:

  • Frequency range: Does the unit selected have sufficient dynamic range for the measurement in question?

  • Sensitivity: What are the maximum and minimum acceleration levels

  • Amplitude Linearity: Is the unit linear across the required measurement range?

  • Temperature range: What is maximum and minimum temperature that the unit will be used at?
